The movements, diving behaviour and thermal environment occupied by female olive ridley turtles Lepidochelys olivacea in
northern Australia were determined through satellite telemetry, during the post-nesting migration. Satellite-relayed data
loggers (SRDLs) were attached to the carapaces of 4 female olive ridley turtles nesting in the Wessel Islands of Arnhem Land
in the Northern Territory of Australia (Graham Island: 11° 45’ S, 135° 57’ E and Wunpirri Island: 11° 36’ S, 136° 05’ E).
This metadata record, represents several different datasets listed hereafter, which can all be accessed through a multi-WFS
CTD - parameters measured by the instruments include time, temperature, and depth. The data represented by this record are
presented in delayed mode.
Diving - parameters measured by the instruments include start and end time and longitude/latitude of each individual dive,
post-dive surface duration, dive duration, maximum dive depth, intermediate dive depths and times. The diving data represented
by this record are presented in delayed mode.
Haulout - a haulout begins when the SRDL has been continuously dry for a specified length of time (usually 10 minutes).
It ends when continuously wet for another interval (usually 40 seconds). Haulout data parameters measured by the instruments
include haulout start and end dates and longitude/latitude, and haulout number. The haulout data represented by this record
are presented in delayed mode.
Argos locations - parameters measured by the instruments include time, longitude, latitude, location quality, along with
other diagnostic information provided by Argos (http://www.argos-system.org/). The Argos data represented by this record are
presented in delayed mode.
Summary Statistics - as well as sending records of individual events such as dives and haulouts, the SRDL also calculates
summary statistics of those events over a specified time period (usually 3, 4 or 6 hours). Summary statistics computed by
the instruments include the proportion of time spent diving, at the surface and hauled-out, the number of dives, and the
average, standard deviation and maximum dive duration and dive depth during each summary period. These statistics are based
on all the data recorded by the SRDL and so are not prone to distortion by variations in the efficiency of transmission
via Argos. The summary data represented by this record are presented in delayed mode. Note that it is impossible to subset
this particular dataset using a bounding box as there is no latitude, longitude coordinates associated with each entry.
This dataset collection combines the following datastreams: CTD, Argos, Haulout, Diving, Summary Statistics.
Prior to October 2015, these datastreams were described and served separately but with new developments of the portal 1-2-3,
they have been combined in a single collection for ease of discovery and data access.
